Duplicating device



Jan. 29, 1963 s. H. PARKER DUPLICATING DEVICE Filed Jan. 23, 1961 INVENTUR. STEWART PARKER BY 4% HIS ATTORNEY 3,075,458 BUPLHIATlNG DEVl'CE Stewart lit. Parker, 1M3 Qolorado St, Salt Lake (City, Utah Filed Jan. 235, 3361, Set. No. 84,234 6 Claims. (Kill. lfil-IlSl) This invention relates to spirit duplicators and, more particularly, to a new and improved spirit duplicator which is very inexpensive to manufacture, extremely so when compared with existing equipment, and which performs very satisfactorily and simply so as to provide two hundred copies and more by the use of a single master suitably disposed on the device.

in the past the spirit duplicating devices of which the inventor is aware have been very expensive both for the manufacturer and for the consumer. Such expense is inordinate where the device is to be used by small clubs, church groups and so forth which send out a limited number of post cards, form letters or other matter regularly to members on a periodic basis. There is a great need for a small, inexpensive device to perform duplicating functions in a simple and convenient manner.

Accordingly, an obiect of the present invention is to provide a versatile, yet inexpensive spirit duplicating device.

A further obiect is to provide a device of the type described which may be easily operated by hand, and be provided with composite means for alternatively depositing a film of duplicating spirits on a sheet of copy paper and then depositing the impression of the master thereon.

A further object is to supply a device wherein suitable means are provided for repositioning the roller of the device so that the wick thereof will always be in a proper position, be it for subsequent fluid deposit or for storage.

According to the present invention the device includes a roller and a handle journalling the roller at its axis of revolution. The roller is hollow and is provided with inlet port means for admitting into the interior thereof a suitable quantity of duplicating spirits. A plug or other stop means is supplied the inlet port, whereas the roller itself is supplied with one or more outlet ports which are in registry with a wick of the device and which are also disposed in communication with the interior of the roller. Thus, duplicating spirits will proceed gradually through the outlet ports of the roller into the wick area so as to be ready for deposit onto a sheet of copy paper.

Either the plug or other fluid stop means, or a separate member, may be affixed to the roller and selectively engage the handle of the device so as to orient the wick appropriately relative to the handle of the device. Likewise, a spring, rubber or other energy storing means may be supplied so as to store sufiicient energy when the device is being rolled over copy paper so as to return the roller automatically to its stop disposition relative to the handle once the rolling is completed and the device lifted from the supporting surface thereof.

In this way the device is adapted to deposit a uniform layer of duplicating spirits onto a sheet of copy paper when the device is advanced in one direction; when rolled in the reverse direction the device deposits the impression of a duplicating master, suitably disposed on the surface of the roller, onto the copy paper supplied.

The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operation, together with further objects and advantages thereof, may best be understood by reference to the following description,

ed ta tent taken in connection with the accompanying drawings in which:

FIGURE 1 is a plan view of the duplicating device of the invention and is shown sectioned and partially cut away for purposes of clarity.

FIGURE 2 is a bottom view of the duplicator of FIGURE 1.

FIGURE 3 is a side elevation of the duplicator of FEGURES l and 2, with a handle being shown in fragmentary view.

FEGURE 4 is a perspective view in reduced scale of the device, illustrating the device as being drawn toward the operator in such a manner that the wick thereof deposits a layer of duplicating spirits upon a sheet of copy paper, for example.

FIGURE 5 is a perspective view of the device, is similar to FEGURE 4, and illustrates the return of the device over that portion of a copy paper formerly receiving duplicating spirits, the progression of the device this time being in a rolling manner so that the impression of a master carried by the surface of the roller of the duplicator is deposited onto the copy paper over the spirits containing area.

In FEGURES 1 through 3 of the device is shown to include a hollow roller it) adapted to contain conventional duplicating spirits and having side journals 11 axially disposed (on axis A) to receive ends 12 of handle The journals ii. are conventional and resemble small, flanged cylinders, the attachment to the sides of container iii being by means of solder or other suitable means (not shown). Thus, the hollow cylinder or roller re is journalled about its axis of revolution A by handle 13.

Roller it? includes one or more outlet ports 14 which are in registry with a wick 15, made of felt or other suitable material, which is glued or otherwise secured to surface S of roller lit in longitudinal disposition as shown. Further, inlet port or aperture 16 is provided in the side of hollow roller iti so as to receive a suitable plug or fluid stopping means 17 as illustrated in FIGURE 1. This plug is selectively withdrawable so that additional spirits may be deposited therein.

It will be noted with reference to FIGURES l, 2 and 3 that the plug 17 also serves to engage and stop handle 13 at a particular disposition of the latter relative to roller ill. The function of plug 17, as a stop means, will be described hereinafter.

it will be noted with respect to FIGURES l and 2 that a spring 123 is fixedly secured to roller 10 at journal 11 by conventional means (not shown) and transversely engages end 12 of handle 13.

The operations of the device will now be described. Suitable duplicating spirits are introduced through inlet port 16 into hollow roller lit and the contents secured by fluid stop means or plug 27. Thus, the duplicating spirits is adequately contained within the roller 10, and the only outlet through the duplicating spirit is through roller apertures M which are in registry with Wick 15.

Sheets of copy paper P are supplied as needed and, as shown in FTGURE 4, the device is drawn in translational (only) movement over copy paper P so as to deposit via elongate Wick 15 a film F of duplicating spirits onto paper P. This is made possible by the drawing of the wick 1.5 across the paper; since plug 17 is in engagement with handle 13, wick 15 will be on the underside of roller lid and the roller 10 will be precluded from rotating during this operation.

When film deposit is completed the operator then rolls the device in the reverse direction as shown in FIGURE 5 so that the master M, previously secured to the sur face S or" roller 10 by masking tape T, or by leaf springs weats or other suitable means, will make the impression onto the copy paper via the spirits. (For purposes of clarity the ends of tape T are shown only, the remainder being broken away to reveal the two edges of master M.) It will be noted that the rolling action will wind spring 18 or other resilient means which functions as follows. After the roller is rolled over the copy paper as shown in FIGURE andis lifted thereabove, the spring will return roller it} to its initial position as shown in FIG- URE S land 2 so that the Wick will be in position for depositing the next film of duplicating spirits upon copy paper as shown in FIGURE 4. Further, if the duplicating process has been completed, then the spring serves to re-orlent the roller with respect to the handle 13 so that the tool may be suitably stored such that duplicating spirits will not leak from the wick.

Obviously other changes could be made in the invention without departing from the scope thereof. Thus, the stopmeans may be a member affixed to roller to which is separated from the member (plug 17) serving to contain the duplicating spirits within hollow roller it). Furthermore, the spring 18 may be one of a variety of configurations; also, a rubber band, for example, may be supplied in lieu thereof and engage handle 13 so that the rolling process shown in FIGURE 5 is sufficient to wind the rubber band, thereby imparting to a sufficient energy to return the roller to a position shown in FIGURE 2 for a subsequent rolling action or for storage.

While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from this invention in its broader aspects, and, therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of this invention.
